Frequently Asked Questions

How is thermal performance handled in high-load environments?

The motor uses a liquid-cooled housing system to regulate internal temperature. This enables reliable operation under sustained torque and high ambient heat conditions.

What safety mechanism is used for load holding during shutdowns?

A holding brake rated at 70.0 Nm provides secure stopping power. It’s designed for vertical axis applications where uncontrolled load movement must be prevented.

Which position feedback system does the MHD112C-024-NP3-AN use?

This model integrates a digital servo feedback (HSF) encoder. It supports relative position detection for high-resolution motion control, requiring homing after power-off.

What kind of shaft interface ensures torque transfer precision?

A keyed shaft is used to mechanically secure the load connection. This ensures alignment under cyclic forces and improves reliability in motion sequences.

What continuous torque rating supports the motor under static load?

It delivers 38.0 Nm continuous torque at standstill. This enables it to maintain position under full load without thermal derating or control instability.
